Vibrating screen is prone to failure and its solution

The vibrating screen is an indispensable equipment in the sand and gravel production line. As the screening operation at the back end of the crusher, its working stability and failure rate have an important impact on improving crushing efficiency, reducing the particle size of crushed products, and reducing production costs. . The working stability and failure rate of the vibrating screen depend on the quality and usage of the vibrating screen. So, what failures will occur in the vibrating screen during work?

According to market adjustments and long-term customer feedback, we found that the main failures of vibrating screens are as follows:

1. The suspension bolt is broken

The vibrating screen mainly relies on vibration to realize the screening of materials. During the vibration process, due to the relatively large degree of freedom of the suspension bolt, it will move horizontally and break due to shear force. To solve this problem, we can reduce the height of the suspension bolts while ensuring the performance of the vibrating screen.

2. The spring is broken

The emergence of the spring problem is also caused by the vibration of the equipment. During the vibration, the bolt produces displacement, coupled with its own vibration imbalance, and then stretches and leads to fracture. The spring positioning seat can be made by using the diameter of the inner ring of the spring.

3. Exciting bearing wear

This is mainly due to the unbalanced vibration of the spring, the entire screen surface not only moves up and down but also moves horizontally, resulting in the wear of the excitation bearing. A damping spring can be added on the side of the spring seat to ensure the running direction of the screen frame and avoid stress on the exciter, thereby protecting the components.

Through the above introduction, I believe that everyone also understands the prone faults of vibrating screens and can solve them well.
